I have tried Microlite's BackupEdge and it seems to write the backup to
tape, but when it tries to verify it keeps asking for the next volume
or says no media detected. Microlite wasn't much help except to say
they had heard similar problems about HPDAT72 drives.

I have tried this on 2 different HP Proliant Servers, the ML370 G4 and
an older ML350 with an external DAT 72 (I have 2 of these drives) same
or similar problem on both machines.

I remember seeing some kind of Sense Data error or something on the
ML350 in syslog too.

I really doubt that both of these tape drives are bad, they are both
new, bought at totally different times, both from Tech Data.

Any suggestions? I couldn't find anything on sco.com or hp.com to help
either.


I'm not sure if this is specific to the internal drive, but FWIW, I'm running OpenServer 6 with a HP DAT 72 external without any problems.
tar, lone-tar, work just fine.

Looks like my firmware revision is newer. Maybe try updating
your drive firmware and see if that helps.
